1.2 All equipment and services shall comply with the mandatory requirements of the Mines Health and Safety Act 29 of 1996 and regulations (as amended). Particular reference is made to Section 21 of the Act which, in terms of sub-clause 4, requires the preparation and submission of a risk analysis before any equipment is delivered, off-loaded or erected on site.
1.3 For general procedures and definitions see Annexure A1 of this specification.
1.4 Specific requirements……..(delete if not required).
2. SCOPE

3.5 Exposed to being hosed with water.
3.6 Exposed to vibration and mechanical shock.
3.7 Maximum air temperature 45ºCMinimum air temperature -12ºC
3.8 Maximum relative humidity Surface: 95%, non-condensingUnderground: 100%, condensing
4. DESIGN CRITERIA AND MATERIAL OF CONSTRUCTION
Page 4 of 43Spec. No. AEL 055
4.1 All electrical equipment shall be suitable for operating on a 3-phase power supply system having the following characteristics:
4.1.1 Nominal voltage 525V
4.1.2 Voltage variations ± 10%
4.1.3 Nominal frequency 50 Hz
4.1.4 Frequency variations + 1 % to –3
4.1.5 Phase rotations Standard anti-clockwise R-W-B
4.1.6 Fault level 35kA
4.1.7 Neutral earthing Via a 63,05 OHM Neutral Earthing Resistorsystem which limits earth fault current to 5 amps.
The fault level specified shall be deemed to be the maximum current occurring at the motor control centres under symmetrical short circuit conditions, on the line side of any limiting device.
The duration of the maximum short circuit currents shall be deemed to be one second.
4.2 AC Supply – Power
Unless otherwise specified, a 525V, 50Hz, 3-phase supply will be provided which will be effectively earthed through a neutral earthing resistor, as indicated above. This should be particularly noted by suppliers of single phase equipment who may not ground any leg of the supply.
Where grounding is required an isolation transformer (not an auto transformer) must be supplied.
Any supplier of Thyristor converter equipment shall take adequate precautions to reduce harmonic distortion feed-back to the supply. It should be pointed out that the 525V supply will carry line borne transient voltages and equipment should be protected against these transients.
It should be further noted that should a supply voltage lower than 525V be available for supplies to control circuits, instrumentation, etc., then this lower voltage supply may not be used for any equipment likely to produce harmonics such as Thyristor power circuits.
4.3 AC Supply – Control and Instrumentation
Page 5 of 43Spec. No. AEL 055
Instruments requiring AC power shall be suitable for 230V, 50Hz operation. This supply will be derived from a transformer fed from the 525V Motor Control Centre or Distribution Switchboard. As such it will be subject to voltage dips and transients. Voltage fluctuations will be in the range of ± 10%. The supply neutral will be solidly earthed.
Supplies for remote instruments should include for a constant voltage transformer (CVT) to protect equipment against line borne transients. In the event of a PLC being supplied as part of the package, a dedicated UPS must be supplied.
All terminals within instruments should be capable of being worked on by instrument personnel, not necessarily with an electrical power background. All live terminals at potentials of 110V or above, should therefore be clearly marked and adequately shrouded to prevent inadvertent contact during testing, etc.

TYPE 1: Underground Moderate Generally dry and hot Low relative humidity Moderately dusty and

Dry haulages away from working areas Dry inclined mine shafts Open cast mines
Paint System: WS 1Abrasive blast to SA 2.5 at bestInorganic zinc silicate primerEpoxy intermediateEpoxy enamel finishing coatThickness: 200μm
NOTES: 1. With the exception of the use of Type 304L stainless steels in Type 5 Plant Severe-Sulphuric Acid, the preferred corrosion protection systems are
applied onto cold rolled mild steel plate with a thickness of 1.6 or 2.0mm. 2. For each type of conditions, two or three corrosion protection systems have been given in descending order of expected performance in the given
conditions. The particular location of the switchgears and/or enclosures, e.g. whether located in dust-free or air conditioned rooms, or whether located in areas outside the specific conditions, must also be taken into account. For example, System 3 may be used with a higher expected performance if the equipment is located in an air-conditioned room within the plant or mine environment.
Page 30 of 43Spec. No. AEL 055
3. The details of the system given in each case are generic. Only approved materials and applicators/vendors should be used and should be asked to submit formal detailed specifications including the following:
Approved brands or types of products Application and curing details Quality assurance procedures, including a Quality Control Plan (QCP) and inspection/testing routines
4. The performance estimates given are based on previous experience and judgement in terms of the various types of conditions. As there are many
different factors that influence performance, e.g. maintenance, mechanical damage, operational procedures, etc., these estimates should only be used as guidelines when the different options, and their cost implications, are being considered.
